When you try to open a compressed or .zip file and extract the contents from a password-protected file, the error 0x80004005 may occur. But, 

Do you know what are the aspects actively working behind this error to have happened?

Any file-zipping software works based on a particular algorithm. If Windows does not support the algorithm, then the error takes place. And it is the primary reason for this unspecified error. Just to let you know, Windows OS supports Deflate, Deflate64, and a few other compressing algorithms.

Here is a great example for you. 

Suppose you have a zip file compressed with the mechanism of Deflate, whereas your friend has a couple of text files where BZip2, LZMA, PPMd algorithms are used. If other conditions are unchanged, you will unzip your file without any hassle, but the ones of your friend will not be unzipped; instead, the Windows will throw an error message.

On a similar note, Windows 10 does not support the encryption method AES-256. Trying to open an AES-256 compressed file may cause you to get the error 0x80004005 message. However, AES-128 and ZipCrypto are supported by Windows.

Though the aforesaid is the prime reason, there are some other causes behind the zip file unspecified error. Let’s have a look at those.

  • Click on the File menu and choose the Exit option from it to close the zip file. In most cases, the users do not do it, which eventually enhances the chance of the file getting corrupted and displaying the unspecified error message.
  • Repeatedly ignoring the error message instead of fixing it may cause the unspecified error.
  • If the zip file is open in the background and you forcefully power off your computer, the file is most likely to be corrupted and damaged permanently.
  • If your system is infected by harmful viruses, they may damage the zip file headers and make them unreadable. 
  • Zip files often get caught by viruses when you transmit them over the network. At that time, you may witness an unexpected zip error.

Though there are manual ways to repair corrupted ZIP files, you cannot use them if the ZIP files are heavily damaged. Hence, for your comfortability and safety, download and use proficient ZIP repair software to your computer.
